Study Notes

Classification of Computers

Classification is based on system performance, which influences physical size and cost.

Categories of Computers

Classification ranges from supercomputers (largest and most powerful) to microcomputers (personal computers).
Categories include: Supercomputers, Mainframes, Minicomputers, Microcomputers (PCs).

Supercomputers

Examples include Cray T3E-900 and GRAPE-4, recognized as the largest and fastest computers.
Primarily used for scientific simulations, research in energy, space exploration, medicine, and industry.
Considered the most expensive computers, often costing millions of dollars.
Frequently found in organizations like NASA.

Monsters

"Monsters" refers to custom-built supercomputers that require specialized technical teams for maintenance.

Mainframe Computers

Very large, powerful, and expensive, serving as tailored systems for larger organizations.
Offers faster processing speeds and greater storage than minicomputers, supporting over a hundred users simultaneously.
Commonly utilized in banks, insurance companies, and corporations.

Minicomputers

Became outdated, popular in the 1960s with capabilities between PCs and mainframes.
Used primarily in small manufacturing plants and research labs.
Allowed multiple users to share processing needs through terminals, with systems mass-produced in factories.

Terminals

Terminals in minicomputers enable shared access to hardware by users.
Typically consist of a keyboard, display screen, and connection wire to the computer system.

Microcomputers (Personal Computers)

Also known as PCs, designed for individual use, available in various designs and forms.
Include components such as a system unit, keyboard, mouse, and display screen, executing multiple tasks.
Mass-produced with options for customization in software and hardware.

Types of PCs

PCs classified based on size and cost include:
- Desktop
- Notebook
- Laptop
- Netbook
- Tablet
- Palmtop

Desktop Computers

Designed for regular use at a designated location, typically near a desk.
Common configuration includes power supply case housing motherboard, CPU, storage, keyboard, mouse, monitor, and speakers.

Motherboard

A printed circuit board containing the CPU, memory, bus, and other essential electronic components.

Disk Storage

Typically comprises hard disk drives, optical disc drives, and older models may include floppy disk drives.

Laptop Computers

Portable computers with a flat display screen, weighing between 1 to 4 kilograms.
Include notable types such as notebooks and sub-notebooks.

Notebook Computers

A portable type of laptop weighing 2 to 4 kilograms with a size comparable to a thick notebook.
Features a large color screen and keyboard, with touch-sensitive pads serving as mice.
Easily transportable, utilizing electric outlets or rechargeable batteries, and can offer similar power to desktops but typically at higher costs.
